What are the common manufacturing processes for creating WPC outdoor armchairs?

WPC (Wood Plastic Composite) outdoor armchairs are popular for their durability, weather resistance, and eco-friendly properties. The manufacturing process typically involves several key steps:

1. Material Preparation: WPC is created by blending wood fibers or flour with thermoplastics like polyethylene or PVC, along with additives for UV resistance and color stability.

2. Extrusion: The composite mixture is heated and extruded into profiles or sheets, which are then cut into components like chair legs, arms, and backrests.

3. Molding: Some parts may be injection-molded or compression-molded for complex shapes, ensuring structural integrity and aesthetic appeal.

4. Assembly: Components are joined using screws, adhesives, or welding techniques, followed by finishing touches like sanding or coating for a smooth surface.

5. Quality Control: Final products undergo rigorous testing for strength, weather resistance, and safety compliance.

These processes ensure WPC outdoor armchairs are lightweight, low-maintenance, and ideal for outdoor use.
